SIPLEEIFICATIUII forming part of Letters Patent No. 668,021, dated February 12, 1901.

Application filed July 14, 1900. Serial No, 23,622. (No model.)

To IK/ZJ/ 707mm, it 712,027 concern.-

Be it known that I, LOUIS K. SCOTFORD, a citizen of the United States, residing at Chicago, in the county of Cook and State of I1linois, have invented a certain new and useful Improvement in Hand-Stamps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improvement in that class of dating or numbering handstamps in which it is desirable to adjust or change the date or number by means of changeable or movable flexible type; and the obj cot is to provide a stamp of this character which will be capable of ready adjustment and will be unlikely to get accidentally changed or have its printing-surfaces become out of alineinent.

The invention consists in the construction, arrangement, and combinations of the parts whereby this object is carried out, and which are more particularly described hereinafter and then definitely claimed.

In the accompanying drawings, which represent one of the ways in which my invention can be put into practice, Figure 1 is a perspective view of my improved stamp with the dieplatein printing position and the parts broken away to show the details of construction. Fig. 2 is a vertical transverse section through the die-plate and its connected parts detached from the stamp proper. Fig. 3 is a cross-section of the same. Fig. 4 is a perspective detail of the drum and one of the spacing-bars for supporting the printing-surfaces.

Referring now to the details of the drawings by numerals,1 represents the main frame of what is known as the tumbler form of hand-stamp, comprising a handle 2 for depressing a yoke 23, which is connected, bymeans of a cross-bar t, with the die-plate 5. This die-plate 5 is adapted to carry the printing-surfaces, which are normally held in contact with the inking-pad, and which die-plate 5 is provided with flanged arms 7, coacting with a short pivoted link 8 and a swinging slotted lever 9, which are so arranged that when the handle is depressed the die-plate is tumbled or turned over to cause the printing-surfaces to contact with the matter to be stamped. The above-mentioned parts, with the exception of the die-plate, need no further description, as they may be of any of the forms now popularly used, although I prefer those shown in the accompanying drawings, as they are of a form recently devised by me as best filling the needs of this style of stamp.

The aforesaid die-plate 5 is formed in two parts, a main base-plate 5 and a supplemental die-plate 6. The plate 5 is flanged at 5, so as to form a recess on the printing side, and the supplemental plate 6, which is like wise flanged, as shown at G, is pivotally connected to the flanges 5, as shown at 5", so that it will swing inside of said flanges 5' and be inclosed thereby, the said flanges 5" strengthening said main plate 5 and affording a means of hinging the supplemental plate 6 to said main plate 5. Projecting from the supplemental die-plate 6 are two grooved studs or pins 10, which when the plates fold together pass through the perforations in the main base-plate 5. Pivoted on the opposite side of the main base-plate 5 are two lockingbuttons 11, each formed with a recess 11 and an ear forming a handle 11". When the recesses 11 coincide with the perforations in the main base-plate 5, the studs or pins 10 project through said perforations and recesses, and the buttons can then be turned until their beveled point-s pass through the grooves in the studs 10, and thereby lock the supplemental die-plate 6 to the main base-plate 5. The purpose of this construction will be fully explained hereinafter. The die-plate (3 is adapted to receive in the recess formed by its flanged sides 6 a spongerubber cushion 9, and the said plate 6 has an opening 6 cut therein, the metal on the sides of the opening being bent into flanges 6 in order to recoive the changeable type, as will appear later. The cushion 9 is adapted to have the rubber die cemented or otherwise secured thereto, but as such is the common practice the die is not shown in the drawings.

Preferably riveted to the main base-plate 5 are two posts or standards 12, and between these standards is formed a large opening 13, preferably of rectangular form. Near the ends of the said posts 12 are formed openings through which passes the crossbar 4:, hereinbefore referred to and on which the die-plate turns.

14 represents a form or drum, preferably formed of sheet metal, provided with integral ears 15, which engage grooved heads of the screws 16, by which this form or drum is adjustably secured to the posts or standards 11, immediately over the opening 6 in the die-plate 6. Secured loosely on this form or drum are the printing-type bands 17, which are of solid high-block type, and between these bands are horseshoe-shaped separating or spacing plates 18. These bands are arranged and adapted to turn on their form or drum, so that any one of their high-block type may pass through the opening 6 in the dieplate 6 and be in the proper printing position.

The foregoing being a description of the construction of my improved stamp, the operation is as follows: Supposing the parts are in the position shown in Fig. 1 and itis desired to change a date or number, the user turns the locking-buttons 11 until their recesses 11 allow the studs or pins to be withdrawn from the perforation in the main base-plate 5,when the die-plate 6 may be swung into the position shown in Fig. 2. There is now nothing to prevent the movement of the bands, and

. the operator can turn them until the proper date or number is in printing position, when the die-plate 6 can be returned to position and looked, as before, by turning the buttons 11. As the die-plate is so locked the new printing date ornumber is firmly held in position by the flanged opening 6, and the type can neither be moved or become out of alinement until the plate 6 is again swung to its outward position. (Shown in Fig. 2.)

By adjusting the grooved screws 16 the form or drumv can be adjusted with respect to the posts or standards and their die-plates, so as to bring the changeable type in the exact printing-plane of the permanent inscription carried by the die-plate 6.

It is obvious that my invention can be applied to other forms of hand-stamps than those of the tumbler Variety, and my claims are therefore not limited to any special form of stamp. It is also manifest that many changes may be made in the details of construction without departing from the spirit of my invention.
